It's all about controlling your breathing, slowing your body down, and should get you snoozing peacefully in no time.

Called the "4-7-8" method, it has been championed by various people and experts, from best-selling author and Harvard trained medical doctor Dr. Andrew Weil, to popular wellness bloggers, according to the Manchester Evening News.

The method is designed to relax you by increasing the amount of oxygen in your blood stream, slowing your heart rate and releasing more carbon dioxide from the lungs.
